Specification of Letters Patent.

' Patented Feb-.8, 1916.

Application filed March 5, 1912. Serial No; 681,680.

To all whom it may concern:

Be it known that I, JOHN PATON ROBERT- SON, a subject of the King ofGreat Britain,

having resided in the United States one year last past and havingdeclared my intention of becoming a citizen thereof, now residing in thecity and county of San Francisco,

State of California, have invented a new and useful Hydrocarbon-Burner,of which the following is a specification.

My invention relates to a novel construction of hydrocarbon burner whichis adapted to be employed in conjunction with the lighter as well as theheavier grades of hydrocarbon and in connection with land, marine or anyother kind of boiler furnaces and one of the principal objects of myinvention is to devise a burner in conjunction with which novel meansare employedfor regulating the strength or length of the flame and alsoto provide a novel burner tip and regulating device therefor which willproduce a complete atomization of the oil.

With the above in view, my invention consists of a novel apparatus forburning light or heavy grades'of hydrocarbon or other oil, wherein thehydrocarbon preferably unmixed with air or other gases is preferablyheated to the desired temperature, until it is discharged from theatomizer, novel means being provided for varying the length of the Incarrying out my invention I do not desire to be limited to anyparticular degree of temperature to which I may heat the hydrocarbon,since I am aware that it is a common right to heat hydrocarbon to thedesired degree by suitab e heating mechanism and to force the same underany desired pressure to a point of utilization.

To the above ends my invention consists of a novel construction ofburner tip having a conical aperture with which is adapted to cooperatea novel construction of conical regulating valve, said valve having itsforward portion guided and seated in a novel construction of disk havingports there-' through and tangential passages coacting with said portsand with said tip, the latter being preferably countersunk at itsdischarge end in order to insure proper combustion at the front of thefurnace.

My invention further consists of a novel construction of burner tip inwhich a desired number of ports open at any desired angle into a valvecontrolled discharge pase sage. I

It further. consists of other novel features of construction, all aswill be hereinafter. fully set forth. I

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme,-since the same has been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of WhlOh my invention consists can be variouslyarranged and organized and that my invention is notlimited to theprecise arrangelnent and organization of these instrumentalities asherein shown and described.

F 1gure 1 represents a longitudinal sectional view of a hydrocarbonburner embodylng my invention. 'Fig. 2 represents a perspective view ofthe tip seen in Fig; 1 1n detachedposition: Fig. 8 represents-indetached position a plan view of the disk seenin Fig. 1. f 1

Similar numerals of reference indicatecorresponding parts in thefigures.

Referrlngto the drawings, 1 designates a caslng having a chamber 2therein, which latter communicates with any suitable source of supplyfor the heated hydrocarbon.

8 designates a packing nut secured preferably in threaded engagementwith the easing 1 andhaving a chamber 4: forpacking or lubricatingmaterial, said packing nut 3 having a cap nut 5 secured thereto, whichis provided withpacking; 6,the, valve stem 7 passing through saidpacking nut and being in threaded engagement therewith, as indicated'at8, the exterior portion v9 of said valve stem carrying a handle orhand-wheel 10 thereon, which is secured thereon by the nut 11 and thepin 12 or other equivalent fastening devices.

13, designates calibrations or indicating .dataon the periphery of thehand-wheel 10, which are adapted to coact with the finger or pointer 14,whose free end terminates in proximity to said calibrations, whereby theamount of opening of the valve 15 can be at all times readilyascertained. A tube, 24, is secured at one end in the casing, l, and hasthe valve-stem extending axially through it. A body 28, is secured uponthe other end of said tube and has an outwardly flaring chamber, 25. Adisk, 17, has an axial bore,

16, in which the valve-stem is journaled, and a rearward extension, 18,and said disk covers the outwardly-flaring chamber 25. The front face ofthe disk is formed with an annular groove, 22, near its periphery, andports, 19, are formed through the disk from said groove to the conicalchamber 25. An annular recess, 21, is formed in the front face of thedisk and surrounding its axial bore, and tangential grooves, 20, areformed in the front face of the disk, extending from the ports throughthe disk to the central recess. A burner tip, 26, has an annularflange,27, and has its rear face bearing against the grooved and recessed frontface of the disk, 17, and said tip has a conical axial seat, 28, for theconical valve 15 upon the valve-stem, which seat has an opening, 29,through the face of the tip. A coupling, 30, is internallyscrew-threaded to screw upon the externally threaded body 23 and has aninwardly projecting annular flange,

s31, engaging the annular flange upon the tip, so that the latter can bedrawn against the disk and body, tightly securing the parts together.

When the parts are in assembled position, as will be seen from Fig. 1,it will be apparent that the valve rod or stem 7 has two bearings, onebeing the threaded bearing in the'nut3 while its forward bearing is inthe opening 16 through the disk 17, theconical extremity 15 of the valvebeing located in the valve seat 28 wherefrom itwill be apparent thatupon the rotation of the handle 10 the flow of the heated oil-throughthe pipe 24 and the orifice 29 can be regulated according torequirements, whereby the strength or length of the flame can beregulated or increased or diminished according to requirements. t willbe apparent that by locating the threaded connection of the rod 7 in theposition seen in Fig. 1, the same is removed as far as possible from theheat of the fire or flame and that there will be no liability of thesame being injured thereby.

v By my novel arrangement of tip, disk, nut and-body portion for thesprayer or atoinizing device which constitutes the burner, the number ofparts is reduced to a minimum and while my invention particularlyrelates to liquid fuel sprayers for burners in which the fuel is sprayedsolely by the agency of pressure, I do not desire to be limited theretoin'every instance, since by my novel construction cold thick oil may besprayed with the same efficiency as any of the lighter heatedhydrocarbon products and I therefore do not desire to be limited in theuse of my invention to any particular kind of hydrocarbon or boilerfurnaces. By the employment of the finger or pointer in connection withthe calibrations 13 the desired adjustment or position of the valve canbe ascertained at all times.

It will now be apparent that l have do vised a novel and usefulconstruction of a hydrocarbon burner which embodies the features ofadvantage enumerated as desirable in the statement of the invention andthe above description, and while I have, in the present instance, shownand described a preferred embodiment thereof which has been found inpractice to give satisfactory and reliable results, it is to beunderstood that the same is susceptible of modification in variousparticulars without departing from the spirit or scope of the inventionor sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

A liquid hydrocarbon burner, comprising I a tubular casing formed withan outwardly flaring chamber, a disk bearing upon the forward end ofsaid casing and. having a rearward extension extending substantiallythrough the flaring portion of said chamber, said disk having a centralbore, a central annular recess in its outer face surrounding said bore,an annular groove near its periphery and ports through its bottomopening into said groove, a burner tip having an exterior flange at itsinner end and seated with its inner face against said disk to cover saidannular and tangential grooves and central recess, and provided with aconical central valve seat terminating in a diverging discharge port, acoupling adjustably connected with said casing and having an inwardlyprojecting flange engagin the flange of said tip, the discharge port ofsaid tip being located outwardly of said coupling, and a conical valvesiidable through said bore and cooperating with said conical centralvalve seat.
